HlTcHlNG-BLOCK.

SPECIFICATION forming part of Letters Patent No. 296,739, dated lApril l5, 1884.

Application filed October 13, 1883. (No mofleLl To @ZZ whom it may concern:

Be it known that I, FRANKLIN GIEEORD, of Springfield, county of Clark, State of Ohio, have invented a new and useful Improvement in Hitching-Blocks, of which the following is a specification.

In the accompanying drawings, Figure 1 is a vertical sectional elevation, representing a bitching device of my invention. Fig. 2 is a similar view taken through aline at right angles from that of Fig. 1, and Fig. 3 is a plan view of the hitch-bolt. In Fig. 4 I have illustrated a modification of the means used for holding the hitch-bolt firm at both ends of its throw.

In each of these ignres letters of like cha-racter indicate corresponding parts.

The object of the invention is to provide a l Y fixed hitching device that when looked is unavailable for that purpose, thereby preventing preoccupation by intruders.

The invention consists in a throw-bolt provided at one end with ahook, slot, or other suitablereceptacle forahitohing-strap,mechanical means for throwing and retaining said throwbolt in its locked and unlocked position, a key for throwing said bolt, and a metallic case for said bolt andv its actuating mechanism, the conguration of said case being such that its exterior surface presents nothing to which a reliable hitch can be made.

The casing is preferably constructed of two parts, a, c. held together with rivets d d and lugs g g', and it is so shaped that a hitching strap or rope cannot be made fast to it when it is arranged for disuse. The hitch-bolt b works in slideways c c o, and it is actuated by a weighted lever, e e f, that is journaled in the casing c c', as shown by the drawings. The rock-shaft j' is provided with a part, h, that may be of any suitable shape, for the accommodation of a key by means of which it can be oscillated to throw the hitch-bolt b. When this part if, of the rock-shaft is constructed as represented, it does not extend to the exterior surface of the casinga, and of course cannot present any catch for the bitchingstrap to rest against. As the hitch-bolt b is thrown out by the aforesaid key for purposes of bitching, a slot, z', extends beyond the exterior surface of the casing, through which the bitching-strap may be passed, and the weighted part e of the lever e has' passed the center of oscillation of the shaft f, and the hitch-bolt bis held to its unlocked position.

`As the bolt b is drawn into the casingaa, the

weight e' passes to the reverse side of the center 0I' oscillation of the shaft f and holds said bolt to its-locked position. The parte of the lever e e passes through a slot, inthe bolt b, by means of which said bolt is actuated.

. In place of the weight o, a spring, q, may be used, into the pocket p of which a point, o, of the lever e may enter when the bolt bis out, and into the pocket p of which the aforesaid point may enter when the bolt is drawn into the casing.

The spring q may be secured to the inside surface of the casing a c by screws fr, or otherwise to suit thetaste of the constructor.

The key by means of which the bolt b is actuated is carried by the owner of the hitching device.

The casing o o is secured to the curbstone or some other stationary object by means of lugs m m and bolts that pass through perforations n fn.

It is obvious that the casing a ci may be cast in one instead of two parts, although the two parts seem'now to be the most preferable inode of construction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is`` e A stationary hitching device having a casing, a o', a weighted lever, e ej, a slide-bolt, b i, working in slideways in said casing, and a key for actuating said bolt, substantially as and for the purpose specified.

, In testimony whereof I have hereunto set my hand this 10th day of August, 1883.

FRANKLIN GIFFORD.
